Teletactica secures $1.5 million in funding

The Estonian-Ukrainian company Teletactica has secured $1.5 million (£1.1 million/€1.3 million) from Green Flag Ventures and MITS Capital, according to a July 17 Green Flag statement on LinkedIn. The funding will help Teletactica expand its production of encrypted and jam-resistant communications for the Ukrainian frontline and eventually Europe. 

The company produces communications links and antennas that are designed to maintain communication throughput in the face of jamming. It has a small form factor, which means it is well-suited for use on UAVs, UGVs, and other small uncrewed platforms. 

The devices are “built for low-latency data streams and offer five times better price-to-performance compared to radios manufactured in the EU and the US. Products maintain packet loss rates as low as 1% to 5%, even under heavy jamming,” the Green Flag announcement states. “We offer resilience under jamming, real-time responsiveness, and large-scale deployability, at a cost that enables rapid mass adoption”, Anton Hetman, co-founder and CTO of Teletactica adds. Maintaining loss rates simply means that the Teletactica products still deliver a high percentage of the data that they are carrying even when jammed. 

Think of it like carrying several heavy bags of shopping through a small doorway. The doorway represents the jamming. With a high loss rate, you might get through with only a few bags – hopefully the important ones. With a low loss rate, you will get through with more of them. 

Telectactia is an alumnus of the MITS Capital Acceleration Programme, which aims to get startups through the early stages of running a business more efficiently. MITS, therefore, led the funding round, which follows on from Teletactica’s pre-seed funding. 

“The core [Teletactica] team pivoted from the private sector and had the experience, skill, and knowledge to identify the frontline EW challenges and respond with unique, flexible, problem-solving solutions that are now being used by multiple units in Ukraine,” said Justin Zeefe, General Partner at Green Flag Ventures.

This type of technology has become important as Russian and Ukrainian jamming is pervasive and effective. Generally speaking, both sides are constantly seeking out a radio frequency that is not being jammed in order to deploy their drones and personnel. Russia, to some extent, will willingly jam its own troops (in what is known as electronic fratricide) if it means achieving an effect on the Ukrainians. So, they are slightly less concerned. But in either case, it places a premium on video and control feeds that are resilient in the face of jamming, and enable the users to deploy their systems in more situations. 

Investor profile: Green Flag

Green Flag Ventures is a venture capital firm focusing on early-stage Ukrainian technology startups that develop “dual-use” technologies. These are innovations with both commercial and strategic (often defense and security) applications, often benefiting from the demanding environment of the current conflict in Ukraine. A key aspect of their strategy is investing in “frontline-proven” technologies, meaning the solutions have been validated and tested in real-world, often combat, scenarios in Ukraine. The firm operates out of Los Angeles, California, and Kyiv, Ukraine, bridging the Ukrainian and US tech ecosystems and was founded by Justin Zeefe and Deborah Fairlamb, together providing expertise in defence, cyber, and early-stage tech as well as in the Ukrainian government and startup ecosystem. 

Together with their team of advisors they manage a $20 million (£14.8 million/€17.2 million) fund, with an investment range typically between $150,000 and $1 million, targeting startups with pre-money valuations from $1 million to $25 million (approximately £700,00 to £18.5 million/€900,000 to €21.5 million). The company notably backs Kara Dag Technologies, which was recently interviewed by Calibre Defence, as well as Himera, a tactical radio manufacturer that has secured contracts with the US DoD. 

MITS is featured in a separate Calibre Defence article, covering the company’s investment in Tencore, a Ukrainian UGV manufacturer. Please check that article out if you’d like to learn more about them. 

Calibre comment

There is a wealth of good ideas and products coming out of Ukraine, often designed solely around a battlefield need, rather than an MoD’s assessment of what the battlefield of the future might need. However, these companies face several challenges in taking their products beyond Ukraine. Not least of them is that they are very obviously focused on meeting their national needs first.

Investment from funds like Green Flag, MITS, and D3 is therefore critical to the survival of this tech as it achieves several things simultaneously: It provides salaries for the Ukrainian teams, many of which operate on a volunteer basis. It also ensures that they can continue the R&D that is necessary for their products to work. It is unfortunate that a lot of Western analysis focuses on what the Russians get wrong, while most Ukrainians reflect on how brutal and effective they are as an opponent. This requires continuous innovation to address their latest capabilities, which in turn costs money. These firms can also provide guidance on international standards and business processes so that Ukrainian companies are well-positioned to provide their goods into the European market when the time comes. 

Without these types of investment, it is very likely that sooner or later these companies will fold and the expertise and capability that has been built through hard battles will be lost. In effect, the work of these funds is helping the West in more ways than most might realise.
